Which colour scheme will have more unity and less contrast?

Correct answer: Analogous scheme

Answer: C, the analogous scheme. An analogous colour scheme uses colours that are next to one another on the colour wheel, such as blue, blue-green, and green. Because these colours share related qualities, they usually blend smoothly and create unity, harmony, and a calm visual flow. Their differences are present but not as sharp as those between opposite colours. A is incorrect because complementary colours are opposite on the colour wheel and normally create strong contrast. B is incorrect because a deliberately strong warm-cool arrangement is designed to create noticeable opposition rather than low contrast. D is incorrect because black and white are far apart in value, producing very high light-dark contrast. C therefore best satisfies both parts of the question: greater unity and less contrast. The word analogous means related or neighbouring, which is the key clue. Memory cue: analogous colours sit together and cooperate; complementary colours face each other and compete for attention.
